Information Asymmetry
Information asymmetry is when one group knows more than another during a deal or interaction, which can tilt the balance of power. This can lead to unfair transactions, market issues, and power imbalances in areas such as finance, health, politics, and education, impacting decision-making and overall fairness.

Elites
Elites are influential, often smaller groups within society, gaining power through resources like wealth, knowledge, or connections. Their presence is felt in politics, economics, culture, and institutions. They can shape public opinion and social change but are also criticized for creating inequality. Their roles and identities vary across societies and times.

Rent-Seeking
Rent-seeking is when someone tries to get a larger slice of the wealth pie, instead of making the pie bigger. It can lead to unfair advantages and slow economic growth. It’s hard to distinguish from normal business, impacts innovation, and can create income inequality, especially in countries with weak governance.
-
Exploitative Interactions
In exploitative interactions, one party derives a benefit at the expense of another. These interactions are prevalent in ecological, economic, and social systems, and are influenced by principles of sustainability and evolutionary dynamics.
-
Theory of Mind
Theory of Mind (ToM) is the ability to understand others’ mental states and predict their behavior. It’s key for social interaction, empathy, and communication. It usually develops in early childhood and its impairment can be seen in conditions like autism.
-
Moral Hazard
Moral hazard refers to situations where a party takes on riskier behavior because they’re shielded from the consequences. It often occurs in insurance, finance, and healthcare, potentially leading to market inefficiencies and higher costs. Strategies exist to mitigate it.

Type 1 and Type 2 Errors
In statistics, Type 1 and Type 2 errors relate to inaccurate conclusions in tests. Type 1 is a false positive, rejecting a true idea, while Type 2 is a false negative, accepting a false idea. Balancing these errors is essential for valid study results.
-
Null Hypothesis
In statistical hypothesis testing, the null hypothesis asserts a lack of effect and serves as a baseline for evaluation. Specific tests are employed to assess evidence, leading to either the rejection or the failure to reject this initial assumption. This methodology is pivotal in both scientific inquiry and rational decision-making.

Principal-Agent Problem
The Principal-Agent Problem occurs when a person (the principal) hires someone else (the agent) to act for them, but the agent may not always act in the principal’s best interest due to differing information or motives. Solutions involve creating better incentives and transparency.
